When trunking PBXware with Magrathea, the process is actually done in two parts:

• Making a trunk which will be used
• Registering an extension(s) which will be used on Magrathea

Making a Trunk

When making a SIP trunk to Magrathea, the following fields need to be set in the exact manner:

• User Type = friend
• DTMF Mode = rfc2833
• Pass-thru mode = Yes
• Host = gk.magrathea.net   (or the one given to you by Magrathea)
• Username = username given to you by Magrathea
• Secret = password given to you by Magrathea
• Register = Not required
• Insecure = very

Registering extension(s) on Magrathea

First of all, you need to connect to the Magrathea server. If on a Linux type:

telnet www.magrathea-telecom.co.uk 777

If using Windows, download freely available Putty. When running it, put the following details in the configuration screen:

• Host Name: www.magrathea-telecom.co.uk
• Protocol:  Telnet
• Port:      777

Make sure that in the Terminal category you select 'Implicit CR in every LF’.
When connected, authenticate yourself by entering:

AUTH username password

Now we will allocate a number or two depending on your preferences. This is done using an ALLO command like in following example:

ALLO 0871696____

In this case, we are telling the system that we need a number starting with 0871696 and having 4 more digits after.
Systems will reply with an available number like 08716961122.
Now we need to activate that number using ACTI command like:

ACTI 08716961122

This will activate this number. Now is the time to link that number to your trunk on PBXware. Issue the following:

SET 08716961122 1 S:[email protected]

Where domain.com is a domain or IP address where your PBXware is located.
Of course [email protected] means that you need to have a 08716961122 DID which will point all incoming calls where you want them.

If you need more numbers to be allocated, repeat ALLO, ACTI and SET commands only with new numbers in them.
